Definitions
- the present invention relates to a magazine for a firearm with a device indicating the number of remaining cartridges.
- the present invention also relates to a firearm equipped with said firearm magazine.
- extension extending from the holster facilitates the capture of the weapon by a third party.
- the extension may also interfere with the user's firing and, therefore, impact the accuracy of the shot.
- the display of the number of cartridges contained in the tank is hidden by the hand or the arm of the shooter when firing. This solution does not allow the shooter to know the contents of the charger while continuing to shoot.
- the present invention therefore aims to provide a simple and effective solution to the aforementioned problems.
- the charger of the present invention allows in particular to be aware of the number of cartridges contained in the magazine of a firearm without having to eject the charger from the magazine slot of the firearm and without having to stop the shoot.
- this charger can easily integrate into most conventional firearms, without causing significant and troublesome modifications of said firearms or the charger used in these firearms.
- the present invention also relates to a firearm according to claims 17 and 18.
- FIG. 1 there is shown a firearm provided with an autonomous charger according to the invention.
- This firearm 100 advantageously has a butt 101 intended to be held by the hand of the user when firing with the firearm.
- An inner housing of said butt 101 is configured to at least partially receive the standalone charger 10.
- the charger 10 has two main parts, namely a main housing 1 and a secondary housing 2 extending under this main housing 1.
- the main housing 1 In the operating position shown in the figure 1 , the main housing 1 is housed entirely inside the stock 101 and the secondary housing 2 forms an underlying extension of the stock 101.
- the secondary housing 2 has was designed so as not to exceed exceedingly the stock 101.
- the height of the secondary housing 2 as measured in a direction perpendicular to the flat bottom end face of the stock 101, will be advantageously lower at 2 cm and preferably less than 1 cm.
- the secondary housing 2 is advantageously provided with an opening 3, through which the number of cartridges contained in the charger 10 is displayed. This opening 3 will advantageously be arranged so that it is directed towards the user when he holds the stick 101 in his hand and that he directs the barrel 102 of the weapon 100 toward his shooting objective.
- the user can know at any time the actual content of the charger, without having to eject the magazine of the weapon and without having to stop shooting.
- the main elements of this charger include a coil spring 4 housed entirely inside a central cavity 1a of the main housing 1, extending from its open upper end 1b to its lower open end 1c, said spring 4 resting on the one hand on the upper face 2a 1 of the secondary housing 2 and on the other hand on an elevator 5 for pushing the cartridges 6 contained in the upper part of the main housing 1 towards said upper end 1b under the action of said spring 4.
- the elevator 5 is thus configured to slide inside said central cavity 1a in a longitudinal axial direction D, as shown in FIG.
- the secondary housing 2 is formed of an upper shell 2a and a lower lid 2b, fixed on the shell 2a by means of screws 2c for example.
- the shell 2a substantially defines a cylinder
- the bases 2a 1 and 2a 3 of substantially oval or oblong shape are connected by a side face 2a 2 .
- the oval or oblong shape of the bases 2a 1 and 2a 3 will advantageously correspond to the shape of the cross-section of the butt 101 so as to harmoniously integrate the magazine 10 with the firearm 100.
- the opening 3 through which the The user can read the value corresponding to the number of cartridges remaining in the magazine is, moreover, advantageously arranged along the side face 2a 2 , and preferably in alignment with the plane dividing the shell 2a in its greatest length .
- the opening 3 will be directly visible by the user when it holds the firearm in its normal operating position.
- the shell 2a is advantageously provided with a structural element 2a 4 disposed projecting at its upper face 2a 1 , said structural element 2a 4 defining a guide rail on which a complementary shape (not shown) ) provided at the lower end 1c of the main housing 1.
- This indicator device 20 is notably housed almost entirely within a cavity 2a 5 of the shell 2a opening on the lower face 2a 3 .
- the indicator device 20 is formed firstly of a flexible connection means 21, of wire or cable type, which is connected at its upper end 21a to a fixing support 5a housed inside the elevator 5
- the position of the fixing support 5a will advantageously be adjustable by means of a screw 5b, whose head 5b 1 will be accessible through a hole 5c formed in the upper face of the elevator 5, as shown in FIG. figure 2 .
- the user can, by more or less screwing or unscrewing the screw 5b inside the fixing support 5a, to modify in a fine manner the position of the fixing support 5a in a direction D 'which is slightly inclined with respect to the axial direction D of the main housing 1.
- this adjustment will in particular adjust the display so that the numbers indicating the number of cartridges in the charger are properly aligned with the opening 3.
- the flexible connecting means 21 is then fixed at its lower end on a rotating drum 22 housed inside the cavity 2a 5 , in particular by means of a cylindrical pin 22a embedded in a hemi-cylindrical housing 22b of said rotary drum 22.
- the fixing may in particular be effected, in the case of a flexible means of wire-type connection as shown on the figure 5 , by knotting the wire 21 on itself at its lower end, said wire 21 having been introduced beforehand into a through hole formed through said cylindrical pin 22a.
- the rotary drum 22 is mounted inside the secondary housing 2 so as to be rotatable about a first hub 2d 1 disposed projecting from the bottom of the cavity 2a 5 , said hub 2d 1 defining an axis of rotation A1 substantially perpendicular to the plane P defined by the upper face 2a 1 and therefore also by the lower end 1c of the main housing 1.
- the rotary drum 22 serves in particular to support the winding of the wire 21 as and when the descent of the elevator 5 under the effect of the weight of the cartridges 6 introduced into the loader 10.
- the rotary drum 22 will advantageously include a first cylindrical periphery 22c 1 , in the form of a pulley, adapted to receive the wire 21 as it winds around the rotary drum 22.
- a first deflection means 23 adapted to pass said wire 21 from a first direction D1, in which it is substantially parallel to the direction D, to a second direction D2, in which it is substantially parallel to the plane P.
- This first deflection means 23 is necessary if one wants to avoid winding the wire 21 around a rotary drum 22 whose cylindrical periphery 22c 1 would be tangent to D1 direction, which would not adequately limit the height of the secondary housing 2.
- the deflection means 23 consists of a cylindrical bar 23 fixed at both ends 23a, 23b to the hull 2a, said bar 23 being disposed inside the cavity 2a 5 so as to be tangent to the direction D1 of the wire 21.
- the wire 21 is partially wound around said bar 21 before moving according to the direction D2.
- the cylindrical bar 23 In order to avoid deterioration or tearing of the wire 21, it will be preferable for the cylindrical bar 23 to have a completely smooth surface state.
- this first deflection means may also consist of a small diameter pulley.
- a second deflection means 24 is advantageously disposed between the first deflection means 23 and the rotary drum 22 so as to reduce the angle of tangency between the wire 21 and the cylindrical periphery 22c 1 .
- This tangent angle corresponds in fact to the angle measured between the direction D2 of the wire 21 and the radius of the circle substantially described by the wire 21 during winding, at the point of contact of the wire 21 with the cylindrical periphery 22c1.
- This second deflection means 24 decreases the risk of a mispositioning of the wire 21 around the cylindrical periphery 22c 1 at the time of winding. He avoids also that excessive bending forces are applied to the first deflection means 23.
- this second deflection means 24 consists of a cylindrical bar fixed at its upper end to the shell 2a, said bar being substantially parallel to axis A1.
- this energizing means consists of a spiral spring 25 which is connected at a first end 25a to a second hub 2d 2 arranged projecting from the bottom of the cavity 2a 5 and at a second end 25b to a second rotary drum 26 rotatably mounted on said second hub 2d 2 and rotatably driven with the first rotary drum 22, the axis of rotation A2 of the second rotary drum 26 being parallel to the axis of rotation A1 of the first rotary drum 22.
- the spiral spring 25 will in particular be configured to oppose the tensile force exerted indirectly by the spring 4 on the wire 21.
- the second rotary drum 26 has a larger diameter than the first drum rotating, 22, so that, during the mutual rotation of the two drums 22 and 26, the angular rotation speed of the second drum 26 is lower than the rotational speed.
- this reduction effect of the second rotary drum 26 makes it possible, in particular, to display a larger number of digits with the aid of a worn display means, or obviously, driven by said second rotary drum 26, which allows the use of the indicator device 20 for loaders of greater capacity.
- the spring spiral 25 is advantageously disposed inside an inner housing 26a of the second rotary drum 26, which avoids using an additional space inside the secondary housing 2 to accommodate said spiral spring 25.
- Such a configuration is only a preferred embodiment.
- Other configurations that may be envisaged may in particular provide for the use of another tensioning means, in particular a spring in compression, or for positioning the spiral spring, or the tensioning means in general, so that it acts directly on the first rotary drum 22.
- the indicator device 20 may also not be equipped with a second rotating drum. In this case, the display means mentioned above will be worn, or in any case driven only by the first rotary drum.
- this torque transmission means consists of a wire 27 connecting the first and second rotary drums 22 and 26.
- the wire 27 is fixed in particular on said rotary drums 22 and 26 so as to be able to wind during their mutual rotation around corresponding cylindrical rims of said drums 22 and 26, namely a second cylindrical periphery 22c 2 of the first rotary drum 22 and a first cylindrical periphery 26c 1 of the second rotary drum 26, each of said cylindrical peripheries 22c 2 and 26c 1 being generally in the form of a pulley.
- the first and second rotary drums 22 and 26 may also be connected by a cable, a tape, a belt or a gear.
- This second rotary drum 26 comprises in particular a lateral face 26c which is defined by two adjacent cylindrical peripheries, namely an upper periphery 26c 1 , which has already been mentioned previously and which allows the winding of the wire 27 serving as torque transmission means, and a lower periphery 26c 2 , substantially delimiting a cylinder of revolution in which a central cavity 26a, serving as a housing for the spiral spring 25, is surrounded by an outer annular flange 26b having several functions.
- Said outer annular flange 26b comprises in particular a first L-shaped cavity 26b 1 , in which the end 25b of the spiral spring 25 is introduced before being fixed on the annular flange 26b.
- said first drum 22 rotates about the axis A1 in the direction of rotation indicated by the arrow F1 of the figure 5 .
- This rotation generates a concomitant rotation of the second rotary drum 26 about the axis A2 in the direction of rotation indicated by the arrow F2 of the figure 5 .
- This rotation produces a torsion of the spring 25, which tends to produce a reverse rotation of the second rotary drum 26 in the direction of rotation indicated by the arrow F3 of the figure 6b .
- the annular flange 26b has a second cavity 26b 2 defining a series of contiguous hemicylindrical housings for receiving a cylindrical pin 26d. Similar to the pin 22a, this cylindrical pin 26d has been configured to serve as an anchor point at one end of the wire 27.
- the user can modify the relative angular positions of the two rotary drums 22 and 26, which will allow a rough adjustment of the display of the value of the number of cartridges through the opening 3.
- the figure 3 also shows that the second cylindrical periphery 26c2 of the second rotary drum 26 has a series of consecutive digits evenly spaced along its circumference. These figures correspond to the number of cartridges contained in the magazine 10. These figures are positioned so as to be visible through the opening 3 formed through the shell 2a of the secondary housing 2, each digit being seen through said opening 3 in a very specific angular position of the second rotary drum 26, and thus also of the first rotary drum 22. These very specific angular positions of the first rotary drum 22 are obtained for corresponding specific positions of the elevator 5. along the axis D, which depend only on the number of cartridges contained in the charger 10. It may however happen that, following repeated use of the charger 10, variations in the restoring force of the spring 4 or the spring 25 occur.
- the figures carried by the second rotary drum 26 may no longer be properly aligned with the opening 3 in the different specific positions of the elevator 5 mentioned above.
- a similar situation could also occur if the secondary housing 2 provided with the indicator device 20 was to equip another type of charger.
- the user should therefore act on the fine and coarse adjustment means mentioned above to adjust both the angular position at the origin of the first rotary drum 22 and the relative position between the first and second drums
- the angular position at the origin of the first rotary drum 22 corresponds in fact to the position of the drum 22 when the magazine 10 contains no cartridge, as shown in FIG. figure 3 . The adjustment of this position is thus obtained by acting on the screw 5b.
- the secondary housing 2 of the present configuration differs in that it has a hub 2d 1 , the hub 2d 2 being replaced by a guide 2d 3 forming a portion raised relative to the bottom of the cavity 2a 5 .
- the guide 2d 3 has, over its entire height, a substantially trapezoidal shape, the convergent sides 2d 31 and 2d 32 of this guide 2d 3 being substantially straight so as to allow the translational guiding of a belt 36, as explained in detail in FIG. following, and the small base of the trapezium, forming a end 2d 33 of the guide 2d 3 , having a profile rounded so as to allow the rotational guidance of said belt 36.
- a leaf spring 37 is advantageously arranged so that it removes the belt 36 from said end 2d 33 .
- the leaf spring 37 has in particular been bent so that its ends are received within slots 2d 2d 34 and 35 formed in the guide 2d 3 at its end 2d 33.
- the belt 36 forms one of the constituent parts of the indicator device 30 intended to display the number of cartridges present in the magazine 10 through the opening 3 of the secondary housing 2.
- This indicator device 30 comprises, in particular, a flexible connection means 31, of type wire, for connecting the elevator 5 to a rotary drum 32, said winding drum, said winding drum 32 being mounted inside the secondary housing 2 so as to be rotatable about the hub 2d 1 along an axis rotation substantially perpendicular to the plane defined by the lower end of the main housing 1.
- the wire 31 Before being wound on the winding drum 32, the wire 31 is first deviated from its path by first and second deflection means 33 and 34 disposed inside the secondary housing 2, said first and second deflection means 33 and 34 being substantially similar to the deflection means 23 and 24 of the previous configuration, both from a structural and functional point of view. Once deflected, the wire 31 is then wound around a first cylindrical periphery 32c 1 of said winding drum 32, said first cylindrical periphery 32c 1 substantially defining a pulley.
- a spiral spring 35 housed inside a cavity of said winding drum 32 is configured to oppose the traction force exerted indirectly by the spring 4 on the wire 31, in the image of what the spiral spring 25 performs in the first configuration described.
- the winding drum 32 further comprises a second cylindrical periphery 32c 2 for driving the belt 36.
- said second cylindrical periphery 32c 2 is advantageously provided, throughout its length, with a series of protuberances in the form of tooth, regularly spaced apart, thus conferring on the circumference 32c 2 the shape of a toothed wheel.
- the belt 36 is successively wound partially around the second cylindrical periphery 32c 2 of said drum 32, guided in rectilinear translation on along one of the sides 2d 31 and 2d 32 of the guide 2d 3 , partially wound around the end 2d 33 and again guided in rectilinear translation along the other side 2d 31 or 2d 32 of said guide 2d 3 before go back to where it started.
- the belt 36 is positioned so that it passes in front of the opening 3 of the secondary housing 2. As illustrated by FIG. figure 7 , the belt 36 can thus serve as a means of displaying the number of cartridges contained in the charger 10.
- the figures may be replaced by a tonnage whose length visible through the opening 3 will indicate in an approximate manner the number of remaining cartridges.
- the numbers or the gauge may also include color codes to clearly indicate to the user that the charger is empty, or virtually empty, or, on the contrary, full, or substantially full.
- the charger 10 may also be useful to equip the charger 10 with a stand-alone lighting device so that the numbers or the gauge can be read in the dark.
- This lighting device can operate using any type of light source, in particular by means of a radioactive source, such as tritium, or a lamp equipped with batteries.

Description
La présente invention concerne un chargeur pour arme à feu muni d'un dispositif indicateur du nombre de cartouches restantes.The present invention relates to a magazine for a firearm with a device indicating the number of remaining cartridges.
La présente invention concerne également une arme à feu équipée dudit chargeur pour arme à feu.The present invention also relates to a firearm equipped with said firearm magazine.
Dans les armes à feu actuelles, des dispositifs indiquant le nombre de cartouches restant dans le chargeur ont été développés. Toutefois, ces dispositifs de l'art antérieur présentent un certain nombre de désavantages.In current firearms, devices indicating the number of cartridges remaining in the magazine have been developed. However, these devices of the prior art have a number of disadvantages.
Ainsi, il existe des chargeurs possédant des orifices numérotés ou des chargeurs transparents en plastique de manière à voir facilement le nombre de cartouches restant dans le chargeur. Cependant, ces solutions exigent l'éjection du chargeur de l'arme à feu pour pouvoir lire ou compter le nombre de cartouches restantes. Ces solutions nécessitent donc plusieurs manipulations du tireur pour qu'il prenne connaissance du nombre de cartouches contenues dans le chargeur. Elles ne sont donc pas adaptées à des situations de risque au cours desquelles il est vital pour le tireur de connaître rapidement et facilement le contenu de son chargeur.Thus, there are chargers with numbered holes or clear plastic chargers so you can easily see the number of cartridges remaining in the magazine. However, these solutions require the ejection of the magazine from the firearm to be able to read or count the number of remaining cartridges. These solutions therefore require several manipulations of the shooter so that he becomes aware of the number of cartridges contained in the charger. They are therefore not suited to risk situations in which it is vital for the shooter to know quickly and easily the contents of its charger.
Pour répondre à cette problématique, d'autres solutions, telles que décrites par exemple dans les brevets
D'autres solutions envisagent également d'utiliser des moyens électroniques pour détecter le nombre de cartouches contenues dans le chargeur et l'afficher sur un dispositif d'affichage externe intégré à l'arme. Ces solutions nécessitent toutefois d'utiliser des chargeurs spécifiques qui sont relativement chers et complexes à fabriquer. Elles ne sont donc pas adaptables facilement sur des chargeurs conventionnels du commerce. De plus, elles nécessitent une source d'énergie électrique.Other solutions also envisage using electronic means to detect the number of cartridges contained in the charger and display it on an external display device built into the weapon. These solutions, however, require the use of specific chargers that are relatively expensive and complex to manufacture. They are therefore not adaptable easily on conventional commercial chargers. In addition, they require a source of electrical energy.

Dans cette configuration, le dispositif indicateur 20 est formé premièrement d'un moyen de liaison flexible 21, de type fil ou câble, qui est relié à son extrémité supérieure 21a à un support de fixation 5a logé à l'intérieur de l'élévateur 5. La position du support de fixation 5a sera avantageusement ajustable au moyen d'une vis 5b, dont la tête 5b1 sera accessible au travers d'un trou 5c formé dans la face supérieure de l'élévateur 5, comme représenté sur la
Par ailleurs, pour faciliter l'enroulement du fil 21, ou de manière générale du moyen de liaison flexible, autour du tambour rotatif 22, il est souhaitable que ledit fil 21, ou ledit moyen de liaison flexible, soit toujours maintenu tendu, en particulier lorsque l'élévateur 5 descend sous l'effet du poids des cartouches introduites dans le chargeur. À cette fin, il est avantageux de prévoir à l'intérieur du logement secondaire 2 un moyen de mise sous tension qui sera destiné à mettre en tension ledit fil 21, ou ledit moyen de liaison flexible. Dans la configuration représentée, ce moyen de mise sous tension consiste en un ressort spiralé 25 qui est relié à une première extrémité 25a à un second moyeu 2d2 disposé en saillie par rapport au fond de la cavité 2a5 et à une seconde extrémité 25b à un deuxième tambour rotatif 26 monté de manière rotative sur ledit second moyeu 2d2 et entraîné mutuellement en rotation avec le premier tambour rotatif 22, l'axe de rotation A2 de ce deuxième tambour rotatif 26 étant parallèle à l'axe de rotation A1 du premier tambour rotatif 22. Le ressort spiralé 25 sera notamment configuré pour s'opposer à l'effort de traction exercé indirectement par le ressort 4 sur le fil 21. De manière avantageuse, le deuxième tambour rotatif 26 possède un plus gros diamètre que le premier tambour rotatif 22, de telle sorte que, lors de la rotation mutuelle des deux tambours 22 et 26, la vitesse de rotation angulaire du deuxième tambour 26 est plus faible que la vitesse de rotation angulaire du premier tambour 22. Comme décrit plus en détail par la suite, cet effet démultiplicateur du deuxième tambour rotatif 26 permet notamment d'afficher un plus grand nombre de chiffres à l'aide d'un moyen d'affichage porté ou, en tout cas, entraîné par ledit deuxième tambour rotatif 26, ce qui permet d'utiliser le dispositif indicateur 20 pour des chargeurs de plus grande capacité. De manière à optimiser au maximum l'espace disponible à l'intérieur du logement secondaire 2, il sera avantageux de disposer le premier et deuxième tambours rotatifs 22 et 26 de telle sorte leur plan médian respectif soit sensiblement aligné entre eux. En outre, le ressort spiralé 25 est avantageusement disposé à l'intérieur d'un logement interne 26a du deuxième tambour rotatif 26, ce qui évite d'utiliser un espace supplémentaire à l'intérieur du logement secondaire 2 pour y loger ledit ressort spiralé 25. Il est clair qu'une telle configuration constitue uniquement un exemple de réalisation préférentielle. D'autres configurations envisageables pourront notamment prévoir d'utiliser un autre moyen de mise sous tension, notamment un ressort en compression, ou de positionner le ressort spiralé, ou le moyen de mise sous tension en général, de manière à ce qu'il agisse directement sur le premier tambour rotatif 22. Par ailleurs, comme représenté par exemple sur les
La rotation mutuelle des tambours rotatifs 22 et 26 pourra s'opérer de plusieurs manières possibles. Elle pourra notamment être obtenue par l'intermédiaire d'un moyen de transmission de couple. Dans la configuration représentée sur les
